Polt vapor barriers are commonly used to prevent moisture from penetrating or moving into your home. Proper crawlspace insulation and encapsulation may repel moisture and keep it from entering your home's closed and non-vented spaces. A crawl space poly sheeting can be an effective vapor barrier for keeping your crawlspace moisture-proof.
Poly sheeting must be continuously laid on the entire crawlspace. A roll of poly sheeting should enable you to cut a large piece, which you can lay on the crawlspace. Overlap the seams by two feet and seal them with poly sealing tape if you need more than one piece of poly sheeting to get the job done. Remember to extend the outside edges towards the foundation wall, and tape them at least six inches above its grade.
Create a tight seal by sealing the poly sheeting to the foundation wall using concrete tape, pressure-treated nailing strip, or construction adhesive, then cap with concrete. Use two inches of concrete on the poly sheeting to prevent it from getting damaged, especially if you want to use your crawlspace for other reasons. Concrete may help prevent the plastic from getting punctured.
